You know that you can wrap your ferromagnetic around a straight conductor and move the PM field in line with that conductor and make electricity

Of course.
It works in the other direction, too - threading a wire through a ferrite bead increases its inductance and reactance to high frequencies. That's how EMI filters are often made.

The old tinman's dug himself into such a deep hole I'm
expecting him to emerge in the U.K.
John.

Oh there you are John.
I have been waiting for days for one of your idiotic comments.
Do you ever plan on doing something useful on this forum?.

Brad, you can't even understand what the implications are when you work with the concept of an ideal voltage source. There is no hope for you.

More words MH--just word's.

Well i have some news for you-->you (and others) have missed/overlooked something regarding your !ideal! voltage source/ideal coil circuit. All to busy looking at what is happening with the coil,and totally missed what is happening with the ideal voltage source

Wonder if your as smart as you say you are MH,and can work out what you missed?.

My words are true Brad. The last couple of posts from you have been clown arguments. I say one thing, and you can't deal with it so your response is about a completely different thing.

There is nothing missed or overlooked regarding the ideal voltage source. Considering your past statements regarding ideal voltage sources, and considering that you could only answer about 10% of the question, I am not expecting a pearl of wisdom to come forth from you.

So the output will be from both values,, the density and the rate in which that density changes,, or moves,, relative to the coil. I have measured this.

It is very difficult to change the flux density without changing the magnetic flux, but it is possible. That's why you conflate these two concepts and your experiments seem to confirm this.

If you make a drawing of the flux lines you can count how many of them penetrate the coil. That count is your flux level.
Flux density is represented by the closeness of these lines.

If you look closely at this video of a superconducting coil (ring), you will notice that the number of flux lines penetrating that ring is constant regardless of the position of the permanent magnet. It also works in reverse.

In the same video you can observe how the flux lines get closer to each other in some places, despite that the total number of flux lines penetrating the ring does not change.

Squishing the lines closer raises the density but may not create an induction event,, adding more lines does and that changes the density and quantity,, adding more into the same volume.

Yes

Your words are false. The only clown here,is you MH(Oh,and your son minnie)
You cower away from any challenge,and argue on circuits that cannot be built or tested.
You have missed something in relation to the ideal voltage source,as your to busy looking only at what the coil dose. A lack of vision has always been your undoing,as it was in the JT thread.

Anyway,you have declined my offer to show us how much better your skills are than mune,and yet you insist that i know so little.
The difference between us MH,is your all talk,and i actually build devices based around what i know.

So you enjoy your self-->perhaps you could take up posting farm animals like minnie

tinman, I've learned a heck of a lot in the last couple of weeks.
You have come out with copious amounts of rubbish.
What about that silly post 302?
Read through post 707, it's cringeworthy!
You're absolutely hopeless at concepts and abstractions.
For me the whole thing has been most enjoyable
Don't give up, go to college, start from day one
I guarantee you'll enjoy it.

Brad,

If you reveal what it is you believe we missed, then we will know. Perhaps it is something that we are aware of already but have not discussed?

I am amazed that those who have only negative things to say about me,are the very same that have nothing to show,or anything of value to contribute to this forum.

You are one of these very people John,all so fast to open your mouth,but not one thing that shows any smarts what so every.

You continue to say how wrong i am,but you have no idea your self as to how things work. You ride on the back of MH and other's. You wait for there answers to question's,and then post your unwanted comment's that have no substance what so ever.

If you went to fight a war,you would be the one standing at the back of the troop's,waiting for them to clear the way.

The part about not being able to place an ideal voltage from an ideal voltage source across an ideal inductor?
Well here is a little research project for you John-->go and find your self an ideal voltage source.
That should keep you busy for a while.

And what is so silly about John.
Do you know the answer?

What are the characteristics of an ideal voltage source Poynt ?.
No series resistance-no resistance to current flow
No inductance--very important
Capacitance?--according to MH-no,as it cannot contain energy,so has no capacity to do so

Do you know what water hammer is Poynt?

No capacitance, no.

Yes. How does that relate?

No in fact my words are absolutely true. You knew beforehand when you made the latest "build challenge" that I was going to say no because I already told you no multiple times before that. It was just a diversion for the umpteenth time to try to weasel yourself out of an uncomfortable situation - you still can't explain how the circuit works in your own words.

I have built stuff in the past and I am satisfied with that. I would feel silly building a pulse motor.

go and find your self an ideal voltage source.

Like you have already been told multiple times now, a good quality bench power supply is an ideal voltage source within certain IV and bandwidth limits. And we are going to ignore your idiotic comment about a bench power supply not being able to hold its voltage steady under load to 0.000001 volts. We already know that, and we already know that for the vast vast majority of experiments we do that we can ignore that.

Go ahead and do your big reveal about the ideal voltage source.

If only you could understand your own circuit.

It is also no surprise that you dare not take anyone up on a challenge.
